I built completly the firefly-rk3288_android5.1_git_20180126.tar.gz.
And I flashed new images form builing.
The android booting is well operated, the linux booting is not operated.
If I try to boot for linux, a recovery screen is shown.

How can I boot to linux?

And... after building, in the lollipop/rockdev/Image-rk3288_box, misc.img, parameter.txt, pcba_small_misc.img, pcba_whole_misc.img files is not updated.
How can I update these files?
